During CNN’s “The Lead” on Wednesday night, host Jake Tapper warned viewers to be critical of claims made by President Trump with a segment listing off “conspiracy theories” Trump has shared in the past.

He told viewers not to make assumptions about whether a spy existed until the Justice Department concludes its investigation into the issue.

“While we await the investigation by the Justice Department’s inspector general into this matter, it is worth remembering that while we are sticking to facts, the president has no such constraints. He simply makes stuff up,” Tapper said.

“He frequently lies and has a long and well-documented career engaging in conspiracy theories about all manner of subjects, with no concrete evidence provided,” he added.
